Guhring 9002050043000 Jobber Drill No. 18 Hss 118 Deg

Product Description

The GUHRING 9002050043000 is a high speed steel jobber-length twist drill bit ground to a 118-degree standard point angle. It carries a wire gauge size of No. 18, which equals 0.1693 inches in decimal diameter. The oxide coating reduces friction and surface adhesion during cutting. Overall length is 80.00 mm (approximately 3.15 inches), with a 47.00 mm flute length and a straight-cylindrical shank diameter of 4.30 mm. Built to DIN 338 tolerances, this bit is manufactured from M2 HSS and features a web-thinned, tapered web geometry that lowers thrust force at entry. It is installed by machinists, maintenance technicians, and metalworking trades for general-purpose drilling applications.

This drill bit is rated for use in cast iron and steel workpieces. The regular spiral, right-hand cutting flute design suits standard vertical and horizontal drilling setups in both bench-top drill presses and hand-held power tools. Maximum drilling depth is 40.55 mm (1.596 inches). The 5xD flute-to-diameter ratio provides adequate chip clearance in typical through-hole and blind-hole operations across production and maintenance environments. Series 205 designates the GUHRING product family for this DIN 338 jobber geometry.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless chuck rated for the shank diameter. Secure the workpiece before drilling and confirm spindle speed is appropriate for the workpiece material and bit diameter. Verify the drill press or tool is powered down and de-energized before mounting or removing the bit. Do not exceed the rated maximum drilling depth without retracting to clear chips.
